This frame from a movie was captured by a star tracker camera on NASA's Jupiter-bound Juno spacecraft. It was taken over several days as Juno approached Earth for a close flyby that would send the spacecraft onward to the giant planet.

During its close flyby of Earth, NASA's Jupiter-bound Juno spacecraft listened for a coordinated, global transmission from amateur radio operators using its radio and plasma wave science instrument, known as Waves.

NASA's Juno spacecraft awaits launch from inside the payload fairing atop a United Launch Alliance Atlas V-551 launch vehicle. Juno and its rocket are at Space Launch Complex 41 on Cape Canaveral Air Force Station in Florida.

At Space Launch Complex 41, the Juno spacecraft, enclosed in an Atlas payload fairing, was transferred into the Vertical Integration Facility where it was positioned on top of the Atlas rocket stacked inside.

NASA's Juno spacecraft is readied for lifting out of a thermal vacuum chamber following testing to simulate the environment of space over the range of conditions the probe will encounter during its mission.

This image of NASA's Juno spacecraft was taken as the vehicle completed its thermal vacuum chamber testing. A technician is attaching the lifting equipment in preparation for hoisting the 1,588-kilogram (3,500-pound) spacecraft out of the chamber.
